To atZZ whom it may concern f suitablemanner. ln the adjacent ends of the Be it known that I, WXLLIAM B.

In Fig. 2 l have repre 55 and Spare, of which the following is a specifi# sented these coupling-piecesas simply driven i cation. into the tubing inthe lower portion of the iig My invention, although it is at present more ure, and in the upper portion of the ligure l particularly intended for ilagpoles,niay be einhave represented them as secured in the tubxo ployed in other taper poles or spare.' ing by rivets a. Any other suitable means 60 The object of the invention is to provide a may be employed forv securing the couplingverylight, strong, and serviceable metal pole pieces within the sections of tubing, Y or spar which is inade in sections, so that it The coupling'pieces B are provided with may be readily transported from place to sockets b, i'orined with female screw-threads, i 5 place, and so that the sections-may be readily and the coupling-pieces G have correspond- 65 connected and disconnected. ing' projections, c, provided with male screw The" invention conssitgtsseiitiaiy,v inapt'rie- *threads Wiiytnesescievvtiireads Athe'sections or spar of taper form, composed ot' sections o which compose the pole or spar may be readily taper tubing, and couplingpieces secured in secured together, so that the adjacent ends of 2o theends ofthesections'oftnbing,andprovided, the sections abutting together` as shown in 70 respectively,y with male and icxnale screw- Fig. 2, form a pole or spar having anapproxithreads, whereby they may be readily coupled Imately continuous and true taper from end to together to form the completed pole or spar, end. I have here represented the flag-pole as and as readily disconnected from each other 'having a cast-metal base-piece, D, which is 25 Whenit is desircdto transport thenil'roln place formed with a cylindric projection, d, over 7c to place. which the lower section A of the pole is ln the accompanying drawings, Figure 1 is driven, or on which it is otherwise secured, an elevation of a dag-pole embodying my Iiny vention, and composed oi' four sections in adand l' have represented thetop section A of the pole as having a cast-metal plug or head, Y 3o dition to the base-piece. Fig. 2 is a vertical section upon a larger scale, illustrating only E, inserted in 'it and secured by rivetsa, or 80 otherwise. l have represented abolt, e, ns .the upper portion of the base-piece and the screwed'into the top head or plug, E, and se- A adjacent ends of sections which are coupled together; and Fig. 3 is a plan of the base-piece.

The pole or spar above described being of The pole or spar consists, essentially, of sec- 'mctal, is almost indestructible, and if emtions A. of metallic tubing, which are of taper fotin and of such diameters that when ployed as a dag-pole will nothave soon to be reset, as will a wood pole because olfA the lower end` of the pole which is set in the ground 4c coupled together they will forinapole or spar rotting off. The'pole also has an additional 9o which is approximately of true taper from bottoni to top, as 1s a wood pole 'or spar. These taper sections of tubing may be 'produced in any suitable way-21s, for example, they may 4 5 be made of spiral riveted or jointed pipe, which is formed by a'strip wound spirally an having the edges ci" 'is convolutions united by riveting or otherwise. *This is a convenient l.
